(57) The method of this invention for manufacturing capsules causes the solution of thermo-getting
material to gelatinize once, and then drys the gel. Therefore the process of manufacturing
capsules is less affected by drying conditions, thus providing capsules of uniform
wall thickness without wrinkle. In the apparatus of this invention, circulating capsule
pins are dipped in the solution of thermo-gelling material, thus the solution adheres
to the pins. And the pins are rotated upside down, thus thickness of the solution
adhering to the pins becoming uniform. Then the pins are retained in the vessel maintained
at a higher temperature than the gelling temperature of the solution, and the solution
adhering to the pins is accelerated to gelatinize. Thus formed gel is dried through
a drying device, and the dried gel, i.e. capsules, is removed from capsule pins.
